  • Figure 1
    Transverse ultrasonographic images
     

    B-mode image adequately visualizing the intimal flap within the common carotid artery lumen.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Dissection;

    A different B-mode image failed to visualize the intimal flap due to its orientation in relation with the ultrasound beam.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Dissection;

    Colour Doppler image showing blood flow signals filling the entire lumen, covering the intimal flap due to overwriting artifact.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Dissection;

    Colour Doppler image with careful adjustment of colour gain detected the intimal flap.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Dissection;

    Colour B-Flow image accurately detecting the flow within the true and false lumen, highlighting the intimal flap.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Dissection;

    Power Doppler image accurately detecting the flow within the true and false lumen, highlighting the intimal flap.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound-Power Doppler; Procedure: Diagnostic procedure; Special Focus: Dissection;

    B-Flow image accurately detecting the flow within the true and false lumen, delineating the intimal flap.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Dissection;
     
     
  • Figure 2
    Longitudinal ultrasonographic images of the carotid bifurcation
     

    Colour Doppler image showing the extension of dissection to the carotid bulb.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Dissection;

    Power Doppler image confirming colour Doppler findings.

     
    Area of Interest: Arteries / Aorta; Imaging Technique: Ultrasound-Power Doppler; Procedure: Diagnostic procedure; Special Focus: Dissection;

    B-Flow image confirming colour Doppler findings and showing improved filling of the blood vessels with blood flow signals.
